'a Ice Patented Oct. 24, -1961 3,005,543 CLEANING PRODUCT Edward A.Morse, Fanwood, NJ., assignor to Personal Products Corporation, acorporation of New Jersey Filed Apr. 13, `1959, Ser. No. 806,113 2Claims. (CI. 206-56) The primary object of this invention is to providean improved means for removing nail polish from the nails of users.

The usual method followed is to wet a small piece of absorbent cottonwith a liquid solvent and' apply it to the nails. The solvent either ispoured from a bottle or other container onto the piece of cotton or thelatter, when attached to a small stick, is dipped into the solvent. Suchliquid preparations are difficult to use, since the amount taken fromthe bottle cannot be accurately controlled. The amount is generally toomuch or too little and, moreover, frequently nds its way onto nailswhich do not require repolishing. In addition, spilling is a commonoccurrence and leads to damage.

Numerous solvents used heretofore as nail polish removers are effectivein removing the polish, but in so doing, dry out the nails and adjacentskin, causing them to become brittle and dry. It is necessary,therefore, to include in formulations `containing such solvents alubricant to offset the drying effect of the solvent.

The present invention overcomes the foregoing and other objections byproviding a small pad (about two and one-half inches long and about twoinches wide) of absorbent material, such as creped wadding tissue,impregnated with a suitable solvent, such as propylene carbonate, whichhas a low vapor pressure. Preferably, the pad is formed with a pluralityof Janus-faced strips or sections (e.g. five on each face of the pad)which may be used individually for the removal of the nail polish. Suchformation of the pad is effected in the course of manufacture byembossing or creasing devices which bond or press the -wadding tissuetogether ou opposite sides at intervals along its length by the use ofhigh pressure, leaving thin vand narrow connecting Webs which act ashinges to permit the absorbent strips to be bent or folded along thehingelines for individual use. The pad is readily disposable after use,and may be made entirely of tissue which disintegrates readily in water.

The amount of propylene carbonate with which the pad is impregnated isvery closely controlled and therefore precludes the possibility ofspilling or forming droplets on the nails as it is used. This solvent isnon-irritating t the skin and will not only remove the nail polish butalso avoid drying out the nails by acting as a plasticizer for the nailsto soften them.

The pad, after being impregnated with the solvent, is placed in a sealedpackage or envelope which is impervious to air, vapor or liquid, such asaluminum or a uoro carbon. This material is entirely compatible with thepropylene carbonate solvent. Clt is proposed to place two pads withineach envelope in order to provide the user with twenty different polishremoving surfaces. The individual packages may be sold as such or soldin larger quantities, say five to a box.

Various other features and advantages of the invention will be apparentfrom the following description and from the accompanying drawings, inwhich FIG. 1 is a plan view of an individual pad showing the bonding anddivision into strips;

FIG. 2 is a transverse section taken on the line 22 of FIG. 1;

FIG. 3 is a plan view of a sealed package containing two Pads; and

FIG. 4 is a longitudinal section taken on the line 4--4 of FIG. 3and-showing the double layer of pads aswell as the `bonding betweenstrips.

Referring to FIG. 1, the pads 10 are produced from a continuous mat ofcreped wadding tissue which is formed and shaped by means of appliedpressure into a series of double-faced strips, such as 19, 20, 21, 22and 23, connected by thin webs, such as 13, 14, 15, 16, 17 and 18located in the central longitudinal plane of the mat. This forming andshaping operation is carried out as a continuous process and alsoproduces thin webs, such as 11 and 12, along the opposite edges of themat. 'Ihese edge webs not only give a neat and finished appearance tothe pad, but they also serve to prevent fraying or unravelling of thetissue strips at the ends.

After being thus formed and shaped, the mat is cut into separateindividual pads, each comprising five different strips as shown in FIG.1 and each strip presenting two polish removing surfaces, one Iat thetop and the `other at the bottom. The webs which connect the fivedifferent strips, namely, the webs 14 to 17, are located in the centrallongitudinal plane of the pad and permit the pad to be turned or foldedin either direction along the hinge lines formed by the webs, so thateither surface of each strip may be used individually in removing thenail polish. The webs 13 and 18 at the opposite ends of the pad 10 arewhat is left on the pad when it is cut from the wadded tissue mat in thecourse of manufacture.

At some stage inthe manufacture, either during or after their formation,the pads are impregnated with a measured amount of the solvent,preferably propylene carbonate, which has all the characteristicsheretofore mentioned.

Thereafter, and as shown in FIGS. 3 and 4, two impregnated pads 10, onesuperimposed upon the other, are enclosed in a protective envelope 9which is sealed along all four edges. -As before stated, this envelopeshould be compatible with the propylene carbonate and may be composed ofaluminum or fluoro carbon which, to repeat, is air tight, vapor tightand liquid tight. Thus, the two-nail polish removing pads are completelyprotected and preserved until the envelope is opened and a pad removedfor use. Once the envelope is opened of course, the solvent will startto evaporate but very slowly I,

because of the low vapor pressureof propylene carbonate.

'I'he envelopes containing the two pads will ordinarily be sold inboxes, say five, ten, twenty-tive, fifty or onehundred to the box.

The invention has been herein shown and described in its preferred formand it is apparent that many changes and variations may be made thereinwithout departing from the spirit of the invention. It is to beunderstood, therefore, that the invention is not limited to any specificform or embodiment except insofar as such limitations are specified inthe appended claims.
